just wondering what i should do, its about to become summer, and this will be the first summer that i have had my cavy. im going to change spark plugs, the oil, and radiator coolant. What i wanted to know was, i read somewhere that its a good idea to flush ur system. I guess that means cleaning it befor eputting any more stuff in. So how would i go about cleaning the radiator coolant? and engine oil tank? is there anything special that i need? and also how much radiator coolant am i looking at here?
 
dont flush the engine. you can buy some radiator flush i believe you dump it in and drive for like a week and then drain it all and refill it. You will need probably one gallon o dexcool coolant and mix it 50/50 which will make 2 gallons it should almost use it all.  
 
 
Don't flush the engine or trans, just the coolant. Use the normal "green" coolant, 
don't go back with that crappy dex-cool it's trouble. I think our cars take something like 12 quarts, mix it 50/50 with water and re-fill.  Plugs/wires/air filter/fuel filter and if you have an auto change the fluid/filter there too.

The backflush kit from Prestone works well.  And yes, Dex-Cool IS OK!  After you run with the flush fluid, drain coolant, install kit ('T' connector in the heater hose), run cool water for 10 minutes, THEN add Dex-Cool.  One gallon of Dex will make about a 60-70% mixture in favor of Dex.  Check with the capacity table in the owners manual.  If used in a clean system, Dex-Cool will not foul you.  I have 180K miles of proof in the driveway.  As for the engine, pour a can of Seafoam in the oil filler tube and drive around for a week.  Change oil as normal, but let it drain for a little longer.  A can of Seafoam in the fuel tank will take care of the fuel system.  What car/engine do you have, anyway?
 
fellow t-dot dog. i myself  use lime away from crappy tire ..it's safe on plastics, rubber and alum, but eats up all the  build ups in the rad  leaving it clean First i drop the used anti freeze add half a can of this stuff and add water filling the rad they go for a 30mins run and drain and fill with 50/50 in the summer and 60/40 in the winter With oil i just go with some cheapie no name oil do the 30 min drive and then drain change the filter and use 10w30 the good stuff...
